Development of a System for Supporting Collaborative Design of Clothes in Virtual Space

本研究旨在以立体显示器为输出装置，以三维指向装置为输入装置，开发一种在虚拟空间中直接操纵服装的环境，以支持服装设计。本研究的主要成果总结如下：1。为了在增强现实环境中使用包括用户的手在内的真实物体来操纵叠加到真实空间中的虚拟物体，需要实现配准，即调整真实空间和虚拟空间的位置和方向。在本研究中，我们实现了确定配准操作虚拟物体可接受误差范围的过程，同时通过用户对虚拟物体的操作，通过交互调整配准，实现了自适应配准以达到可接受误差范围。通过对真实物体的观察，获得描述可变形物体在操纵下的三维形状的虚拟物体模型。为了实现这一目标的第一步，我们实现了估算模型参数的过程，该过程可以再现由相机在垂直平面上操纵的类似真实物体的字符串观察结果所获得的3D形状。基于虚拟空间直接操纵的服装设计系统的开发我们开发了一个通过在虚拟空间中直接操纵服装的三维形状来设计服装二维图案的系统。在我们的服装设计系统中，用户首先选择由典型图案构成的服装模型，并在虚拟空间中通过操纵来修改其三维形状

The objective of this research is to develop an environment to support clothes design based on direct manipulation of clothes in virtual space by using a stereoscopic display as the output device and a three dimensional (3D) pointing device as the input device. The major results of this research are summarized as below :1. Interactive Adjustment of Registration for Augmented Reality though Virtual Object Manipulation In order to manipulate virtual objects superimposed into the real space using a real object including the user's hand in an environment with augmented reality, it is necessary to realize registration, which is to adjust the positions and orientations of the real space and the virtual space. In this research, we realized the process that determines the acceptable range of errors for the registration to manipulate virtual objects and realizes the adaptive registration to attain the acceptable range at the same time by adjusting the registration " interactively though virtual object manipulation by the user.2. Virtualizing Shapes of Deformable Objects under Manipulation from Real Observation It is aimed to obtain a virtual object model that describes 3D shapes of deformable objects under manipulation from observation of real objects. For the first step toward this goal, we realized the process to estimate the model parameters that reproduce the 3D shape obtained as the results of observation of string like real objects manipulated on a vertical plane by a camera.3. Development of Clothes Design System Based on Direct Manipulation in Virtual Space We developed a system to design 2D patterns of clothes by direct manipulation of the 3D shape of the clothes in virtual space. In our clothes design system, the user first selects a model of clothes constituted by typical patterns and modifies their 3D shape by manipulating them in virtual space
